IMPROVEMENT IN BASE-BURNING- STOVES.

The Schedule referred'to in these Letters Patent and making part of the same To all whom it may concern Be it known that we, FRANK Z. OBERMEYER and VVILLLAM HALLE, of the city and county of Milwaukee, and State of Wisconsin, have invented a new and useful Improvement in Base-Burning Furnaces; and we do hereby declare that the following is a full, clear,

' and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side view of our invention;

Figure 2 is a sectional View; and

Figure 3, a sectional view of the top part of the furnace in the line as x, fig. 1, inverted.

Similar letters of reference, in each of the figures, indicate corresponding parts.

The object of our invention is to produce a baseburning furnace superior in its heating-qualities. This furnace is to be enclosed in brick, and the hot air which shall surround it conveyed wherever wanted for heating-purposes.

A is the coal-magazine.

B, the base of the furnace.

O, the spout through which coal is conveyed to the magazine.

D D D, smoke and heat-pipes in the lower part of the furnace.

E E E, smoke and heat-pipes of the upper part of the furnace, connected, by a socket, with the lower pipes.

F, water-tank-surrounding pipes E E E.

G, water-reservoir outside of brick-work. This water-reservoir is just as high as the inside tank, and is connected with the tank F by the. pipe H, through which water is conveyed from reservoir G.

1, upper part of the furnace.

K, a drum on top of the furnace.

L, partition hanging down from the top of I. M, pipes from I to drum K.

N, inside partition to I.

0, straight draught from the coal-magazine.

P, damper in the straight draught.

Q, handle to damper P.

It, door through which soot may be cleaned out of I.

S, pipe on top of drum K, for the draught.

T, supporting-braces.

U, the fire-chamber, made larger than the coalmagazine, and on the top of which sets the smoke.- pipes D, the openings of smoke-pipes D being free, so that the soot can fall down, and not accumulate, and stop the draught.

V, brackets on pipes E, to hold upthe water-tank.

Operation.

Set the furnace in a brick case; put in any grate suitable. Then put your coal in through the spout C, and build a fire in the furnace. Then you can open damper P, and let the draught go straight up through the furnace, or keep the damper closed, aud'the draught will go up through pipes D and E, down into I, below partition L, and up again, through pipes M, to drum K, and then out through pipe S.

. What we claim as our invention, and desire to secure by Letters Patent, is-

1. Magazine A, fire-chamber U, pipes D and E, upper furnace I, partition L, drum K, and outlet-pipe S, substantially as described.

2. Magazine A, fire-chamber U, pipes D and E, upper furnace I partition L, drum K, water-reservoir I and damper I, constructed and arranged substantially as described.
